NSDictionary *info = [ASSETHELPER getGroupInfo:_groupArray[indexPath.row]];

[imgView.layer setCornerRadius:25];
[imgView.layer setMasksToBounds:YES];
[imgView.layer setBorderColor:[UIColor whiteColor].CGColor];
[imgView setImage:[info objectForKey:#"thumbnail"]];
[cell.contentView addSubview:imgView];
UILabel *label=[[UILabel alloc]initWithFrame:CGRectMake(80, 20, 200, 30)];
[label setText:[info objectForKey:#"name"]];

Answer 1

Try this code .You have used dequeueReusableCellWithIdentifier:
NSString *CellIdentifier = [NSString stringWithFormat:#"Cell %d",indexPath.row];
UITableViewCell *cell=[self.tableView cellForRowAtIndexPath:indexPath];
if (cell == nil)
{
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}

Answer 2

You can try with it. Just remove the previous contentView after create a table cell.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (cell==nil)
{
cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
//****add this code*******//
for (UIImageView *v in [cell.contentView subviews])
{
[v removeFromSuperview];
NSLog(#"%# hello \n\n\n\n\n%#",v,[cell.contentView subviews]);
}
for (UILabel *v in [cell.contentView subviews])
{
[v removeFromSuperview];
NSLog(#"%# hello \n\n\n\n\n%#",v,[cell.contentView subviews]);
}/////////
cell.selectionStyle = UITableViewCellSelectionStyleNone;
NSDictionary *info = [ASSETHELPER getGroupInfo:_groupArray[indexPath.row]];
UIImageView *view;
if (indexPath.row % 2)
{
view=[[UIImageView alloc]initWithImage:[UIImage imageNamed:#"dark_bg"]];
}
else
{
view=[[UIImageView alloc]initWithImage:[UIImage imageNamed:#"light_bg"]];
}
cell.backgroundView=view;
UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(10, 10, 50, 50)];
imgView.backgroundColor=[UIColor clearColor];
[imgView.layer setCornerRadius:25];
[imgView.layer setMasksToBounds:YES];
[imgView.layer setBorderColor:[UIColor whiteColor].CGColor];
[imgView setImage:[info objectForKey:#"thumbnail"]];
[cell.contentView addSubview:imgView];
UILabel *label=[[UILabel alloc]initWithFrame:CGRectMake(80, 20, 200, 30)];
[label setText:[info objectForKey:#"name"]];
[cell.contentView addSubview:label];
return cell;
}
